We believe that each day is an opportunity to support one another, to support our clients, and to support our communities. If you feel the same, then you’ve found your future.

We are seeking a highly motivated and experienced Drinking Water Project Manager to lead and deliver complex water infrastructure projects that support safe, reliable, and sustainable drinking water systems.

• Oversee planning and design efforts for water storage infrastructure, including elevated tanks, ground storage reservoirs, and clearwells, ensuring operational efficiency and long‑term reliability
• Evaluate and design treatment solutions for PFAS and other emerging contaminants, incorporating technologies such as granular activated carbon (GAC), ion exchange, and membrane systems
• Conduct and supervise hydraulic modeling, system capacity analyses, water distribution master planning, and lead service line inventory and replacement programs
• Perform water quality assessments and support compliance with federal and state drinking water regulations
• Manage project teams, including internal staff and subconsultants, while maintaining responsibility for scope, schedule, budget, and quality
• Prepare and present technical reports, plans and specifications, cost estimates, and client‑facing deliverables
• Coordinate with regulatory agencies and support permitting efforts, including engagement with environmental and public health stakeholders
• Provide construction‑phase services such as submittal review, RFIs, field observations, and startup/commissioning support
• Mentor and develop junior engineering staff, fostering technical growth and knowledge sharing across the team
• Build and maintain strong client relationships while supporting proposal development and strategic

Skills, Knowledge and Expertise

• Bachelor’s degree in civil, Environmental, or related Engineering discipline
• Professional Engineer (PE) license required, or ability to obtain within 6 months
• 8+ years of progressive experience in drinking water system planning, design, and infrastructure projects
• Strong expertise in water distribution hydraulics and modeling tools (e.g., WaterGEMS, InfoWater, EPANET)
• Demonstrated experience with water storage system design, including coordination with structural and operational considerations
• Familiarity with PFAS treatment technologies and evolving regulatory frameworks is highly desirable
• Comprehensive knowledge of water treatment processes, including filtration, disinfection, and advanced treatment systems
• Proven ability to manage multiple projects simultaneously while delivering high‑quality results on time and within budget
• Proficiency with engineering and design tools such as AutoCAD and GIS preferred
• Experience with funding programs (e.g., State Revolving Fund, USDA Rural Development) is a plus
• Excellent communication, leadership, and organizational skills, with the ability to engage effectively with clients, regulators, and team members
